Answer:

Explanation:
When you have a square root number, it should look like this:


Then you're asking how to solve it, simple.
All you have to do is find a number that times itself twice to get that specific number.
Let's look back at the examples I gave you:

This means that you need to find a number that multiples itself twice to get 4.
In this case, it would be two, so:
2 x 2 = 4
= 2
So remember, when you have a square root, you have to find a number that multiples itself twice to get the number in the square root
